1 all' whom it may concrn:

Be it known that I", WILLIAM BAYLES, a

I' citizen of the United States, 'resid-ing at v Drying Lumber Under Pressu're, of which the followingis a specification;

The object of my said invention 'is the provision of easily applied and manipulated means for holding lumber in a straight of this specification, in which F igure 1 is a perspective showing the means constituting the preferred enb odiment of my invention in use.

Figure 2 is a fragmentary end elevation of the same on an enlarged scale.

Figure 3 is an enlarged fragmentary perspective showing the end portion of one of the lower cross bars of the means.

Figure 4: is an enlarged detail showing one of the springs between the upper cross bars.

Figure 5 is an enlarged horizontal sec- 'tion taken in the plane indicated by the line 5-5 of Figure 2 and showing one ot' the retractile springs. 4

Figure 6 is a detail view illustrative of the use of my novellever for applying my novel means.

Figure 7 is a detal perspective lever; I

Figure 8 is a detail longitudinal section of the swingable member on the lever.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

I show in Figures 1 and 2 a bundlel of lumber such as is placed in a kiln to be dried.

My novel means for the purpose indicated comprises in the preferred embodiment of my invention lower cross bars 2 of channel type, having end slots 3 in their of said topwalls asillustrated. Thesaid means also comprses pai'rs 'of upper cross bars 4 and 5. These bars 4: and 5` are arranged in` reverse positions so as to tend to co'nfine be tween the same expansi'on Springs 6 a nd7;

the intermediate expansion spring of each pair being arranged about midway the length thereof' and being held againstshifting when deemed necessary by pins (not v shown) on the bars 4 and 5. Bolts 7 extend through the end' portions of the bars 4: and 5 and also through the springs 6 and are provided wit-h-nuts 8 and eyes 9, the said eyes being-tor the connection ot the-upper slidable members 10 of the retractile springs 11, the other slidable members of the said springs being designated by 12. connected to and depending from the members 12 of the retractile springs are rods 13 to which me connected pendent chain sections 14:. These chain sections 14 are designed to be placed in the slots 3 of the lowerr bars 2 for the connection of the chains to\ the bars 2 and for the maintenance of the holding means under considerable tension about the b undle of lumber 1.

For the tensioning of the holding and pressing means I provide a novel device 'shown in detail in Figures 6, 7 and 8. Said device is: mader up of a hand lever 15, b ifurcated at its forward end as designated by 16, and a swingable member 17, pivoted at 18 to the lever 15 and having a bifurcated head 19 and also having in the inner sides of the spaced portions of said head recesses 20 that are opened at their lower ends.

he nanner of using the appliance just described is illustrated in Figure 6 and by rei'erence to said figure it wll be noted that the lever 15 s adapted to be: engaged with the chain and with the underside of -bars 2 by arranging certain Links of the chain at right angles to the Slots 3 as clearly shown in Figure 6.

lt will be manifest from the foregoing that my novel means while simple and inexpensive in Construction is capable of performmg the functions ascrbed to t, and

is susceptibie of being appiicd and removed Without the employment ei? sklled labor; also, that by the use of the lever appiiance shown in Figures 6 to 8, the means may be not only appiied in the manner described but may be tightened whenever occasion demands.

VJhile I prefer the specific Construction heren disclosed, I do not desire to be understood as confining myself to the same, the scope of my invention being defined by my appended claims within which modifications may be made Without departure from my nvention.

Having described my invention, What I claim and desire to secure by Letters Patcnt, is

1. The combination of a pair of' reversely arranged and opposed channel bars, expension springs spaced, &part and interposed and confined between said bar-s, retractie means connected to the retractile springs and adapted tobe adjustably and detachabiy connected to the third-named bar djacent to the ends thereof.

2. The combinaton of a` pair of reversely arrenged and opposed channel bars, expen-` sion sp'ngs spaced &part and nterposed and confined between seid barsybolts ex-i' tending 'through the end eXpa-nsion springs and the said bars, retractle springs connected to seid bolts, chains connected With said retractiie springs, and a third channel bar adapted to be arranged at the opposite side of a bundle of lumber to the first-named bars and having end Slots for the adjustable and dctachable anchoring of the chains.

In testimony Whereof I ax my signature.

WILLIAM BAYLES.
